Integrated Circuit for Cqi Reporting in Wireless Communication

1. A mobile terminal, comprising: circuitry, which, in operation, generates CQIs for each subcarrier (SC) group of multiple subcarrier groups, a plurality of subcarriers consecutive in a frequency domain being grouped into the multiple subcarrier groups; and a transmitter, which, in operation, reports CQIs in inconsecutive time resources, the reporting CQIs in inconsecutive time resources including: reporting, at a first periodicity, first respective CQIs of the multiple SC groups; and reporting, at the first periodicity, second respective CQIs of the multiple SC groups, wherein reporting of a first and a second CQI of a SC group of the multiple SC groups occurs at a second periodicity which is greater than the first periodicity.

2. The mobile terminal of claim 1 wherein the transmitter, in operation, cyclically reports respective CQIs of the multiple SC groups in inconsecutive time resources.

3. The mobile terminal of claim 1 wherein the SC group for which the CQI is reported changes in accordance with the first periodicity.

4. The mobile terminal of claim 1 wherein at least two of the respective CQIs are reported at a determined interval.

5. The mobile terminal of claim 1 wherein at least two of the CQIs are reported per a determined number of transmission time intervals (TTIs).

6. The mobile terminal of claim 1 wherein subcarriers of a SC group are consecutive in the frequency domain.

7. The mobile terminal of claim 1 wherein a SC group includes a plurality of resource blocks, and subcarriers of a resource block are consecutive in the frequency domain.

8. The mobile terminal of claim 1 wherein a SC group includes a plurality of subbands, and subcarriers of a subband are consecutive in the frequency domain.

9. The mobile terminal of claim 1 , comprising: a receiver, which, in operation, receives information indicative of the first periodicity.

10. The mobile terminal of claim 1 wherein a first respective CQI of a SC group is different from a second respective CQI of the SC group.

11. A method, comprising: generating, by a mobile terminal, CQIs for each subcarrier (SC) group of multiple subcarrier groups, a plurality of subcarriers consecutive in a frequency domain being grouped into the multiple subcarrier groups; reporting, by the mobile terminal, CQIs in turn in inconsecutive time resources, the reporting CQIs in inconsecutive time resources including: reporting at a first periodicity, first respective CQIs of the multiple SC groups; and reporting at the first periodicity, second respective CQIs of the multiple SC groups, wherein reporting of a first and a second CQI of a SC group of the multiple SC groups occurs at a second periodicity which is greater than the first periodicity.

12. A non-transitory computer-readable medium having contents which configure processing circuitry to perform a method, the method comprising: generating CQIs for each subcarrier (SC) group of multiple subcarrier groups, a plurality of subcarriers consecutive in a frequency domain being grouped into the multiple subcarrier groups; reporting CQIs in turn in inconsecutive time resources, the reporting CQIs in inconsecutive time resources including: reporting at a first periodicity, first respective CQIs of the multiple SC groups; and reporting at the first periodicity, second respective CQIs of the multiple SC groups, wherein reporting of a first and a second CQI of a SC group of the multiple SC groups occurs at a second periodicity which is greater than the first periodicity.
